UPDATE Yahoo have said they can't help me because I can't give them an IP address for my mail server. I've asked if this means mail from every other distributed system is likewise blocked (Azure, SES, Hotmail, Gmail) so it will be interesting to see the response to that. But it looks like I need to resolve this some other way.
>From the responses here, only one other Appengine user is seeing this behaviour, so I'm guessing some other issue is at work. That issue isn't that I send spam, by the way - all my messages are transactional and requested by the user, although some less sophisticated users may have marked them as spam. Possible issues: 1. Volume. We send about 2000 emails a day at the moment. Could the other blocked app, and any unblocked apps comment? 2. I set up a DKIM DNS record when Google released DKIM for Apps, only to find it didn't work for Appengine. I've left the DNS record in place and my Google Apps (Gmail) messages are NOT blocked. Possibly having a DKIM DNS record but no DKIM headers get messages blocked - again could the other blocked app, and any unblocked apps comment? 3. Country. I don't think NZ is a particularly bad spam haven, so this is unlikely.
